Application rleil April 538, 1399- Serial No. 711,865. (1% model.)

the motive agent, the carburetor being ara new and ranged to permit the operator to accurately regulate the proportion of gas and air to onrich the air according to the requirements of the engine,

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter end then pointed out in the cleims.

A practical embodiment of my invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding perts in both the views,

Figure 1 is a, sectional side elevation of the improvement, and Fig. 2 is a, sectional plan view of the some on the line 2 2 in Fig. l.

The improved cerbureter is provided with a, tank A, .adapted to contain gasolene or other oil for enriching the air passing into and through the tank by we of a vent or filling-plug B on the top of the tank 0n liquid in the tank A is arranged at heat C, provided at its middle with on upwurdlyextending pipe D, having-en easy sliding lit in a pipe E, socuredto the top of the tank A, and provided outside of the tank with a pipe F, leeding to the engine or other machine in whichthe enriched gas is to be used.

Inside of the pipe D is securcdu nozzle G, opening at its lower end into the liquid contuinedin the tank A, the upper or discharge end of the nozzle being above the inlets 1) formed on the pipe D a short distance shove the float C. A needle-valve Hserves to regulate the amount of oil passing through the nozzle-opening, said needle-Volvo extending outside of the nozzle-opening and in an up ward direction and having a screw-thread H on its stein H said screw-thread screwingin the upper threaded end of the pipe D, as is plainly illustrated in Fig. l.

The upper end 0)? the pipe D has outlets or openings D which open into the upper portion of the fixed pipe E, so that the enriched air can pass from the pipe ID through said openings D into the upper part of the pipe E and from the latter by the pipe F to the engine, which draws the gas during the suction period of its piston.

The stein H of the needlevslve H extendsthrough a. stufing-hox E iu'the top of the pipe E, and on the outer end of said valvestem H are adopted to he supported weights lt'or holding the float C with more or less force down in the liquid'contuined in the tank t ity to the outlet of the nozzle G,

Now it is evident that when the engine is i started the suction caused in the upper end of the pipe'E causes the air to pens through the inlets 1') into the pipe D and over the up per portion of the nozzle G to createusfiction therein to draw the liquid up in the nozzle and through the nozzle-opening thereof to finally mix with the eutwardly-ruehing air to form an explosive charge. The air thus enriched passes through the upper end of the pipe 3') end-tho outlets D to the upper ondof the pipe E and the pipe F to be drawn into the engine. As the pipe D, curried .hy the 1 flout C, has an easy sliding fit in the pipe E, it is evident that the float rises and falls with the liquid in the tank, and us the needle-valve stem is adjustable in said pipe and is weight- I claim as new uud desire to secure by Letters Patent- 1. A carbon rotor, comprising a tank for conmining liquid, a float on said liquid, an airpipe carried by the float and having air-inlets and gas-mixture outlets, and a nozzle in said pipe and opening at its lower end to the liquid and extending at its upper end above thoriulets in said pipe, substantially as shownaud described.

2. A carburetor, comprising a tank for containing liquid, a float on said liquid, on air pipe carried by the float and having airdulets and gas-mixture outlets, a nozzle in said pipe and opening at its lower end to the liquid and extending at its upper end above the inlets in said pipe, and an outlet-pipe in which the air-pipe is fitted to slide, and which outlet-pipe is carried by the tank and onneeted with the engine, substantially as shown and described.

3; A earbureter, comprising tetank for containing liquid, a float on said liquid, an airpipe carried by the float and having air-inlets and gas-mixture outlets, a nozzle in said pipe and opening at its lower end to the liquid and extending at its upper end above the inlet-sin. said pipe, and a valve for controlling the on tlet end of said nozzle, substantially as shown and described.

4. A carbureter, comprising a tank for containing liquid, a float on said liquid, an airpipe earriedbythe float and having air-inlets and gas-mixture outlets, a nozzle in said. pipe and opening at its lower end to the liquid and extending'at its upper end above the inlets in .said pipe and a valve for controlling the out-let end of said nozzle, the stem of the valve being threaded to sereivin said pipe, said stein also extending to the outside of the tank, to adjust the valve relatively to the nozzle, substantially as shown and described.

5. A carbu reter, comprising a tank for containing liquid, a float on said liquid, an airpipe carried by the float and having air-inlets and gas-mixture outlets, a nozzle in said pipe and opening at its lower end to the liquid, and

extending at its upper end above the inlets in said pipe. a valve for controlling the outlet end of said nozzle, the stem of the valve being threaded to screw in said pipe, said stem also extending to the outside of the tank, to

adjust the valve relatively to the nozzle, and weights adapted tobe secured to the outer end of said stem, as set forth.
